I'll stick with the term "policy of targeted killing" - and line up with those English-deficient Israelis, Russians and USAians.

E.g., Steven R. David, “Fatal Choices: Israel’s Policy of Targeted Killing.” The Begin-Sadat Center for Strategic Studies: Mideast Security and Policy Studies No. 51 (September 2002): p.2:

Targeted Killing: the intentional slaying of a specific individual or group of individuals undertaken with explicit governmental approval.
In any event, best wishes for your journal.
